26 Years Behind the Bar
A Course Created by BartenderGirl.com
A complete mobile bartending course built from two and a half decades of real events, real clients, and real craft — from your first shake to your first booking.
Begin the CourseEvery great bartender starts here. Learn the tools, spirits, terminology, and techniques that form the backbone of the craft. Master these and everything else becomes second nature.
Whether you're setting up a permanent bar or loading your mobile kit into a van at 5pm, the tools you carry define what you can make. Here's everything you need — and why each piece matters.
Pack your kit in a dedicated rolling case with everything in the same slot every single time. At your 50th event, you'll be setting up in the dark and you won't have to think. Muscle memory saves the night.
You don't need to memorize every distillery. You need to understand the character of each spirit category well enough to recommend, substitute, and build cocktails confidently.
| Spirit | Base | Flavor Profile | Key Cocktails |
|---|---|---|---|
| Vodka | Grain/Potato | Neutral, clean, slight sweetness | Martini, Mule, Bloody Mary |
| Gin | Grain + Botanicals | Juniper-forward, herbal, floral | Negroni, G&T, Tom Collins |
| Rum | Sugarcane | Sweet, molasses, tropical | Daiquiri, Mojito, Dark & Stormy |
| Tequila | Blue Agave | Earthy, sweet, vegetal | Margarita, Paloma, Tequila Sunrise |
| Mezcal | Agave (various) | Smoky, complex, roasted | Mezcal Negroni, Oaxacan Old Fashioned |

Unless your client specifies premium spirits, build your mobile bar around reliable mid-shelf bottles. Ketel One, Tanqueray, Bacardi Superior, Espolòn, Bulleit, and Martell VS cover 90% of what you'll be asked for. Never show up with only one whiskey option.
Learn one signature cocktail per spirit category that you can execute flawlessly in under 60 seconds. At a busy wedding, speed and consistency are your reputation.
Free pouring looks impressive — and at high-volume venues it's necessary — but at mobile events, jigger every drink until you can pass a pour test blindfolded. A standard free pour count is 4 counts = 1oz at a 45° angle. Practice with water and a jigger to calibrate.
Ice is an ingredient. Use fresh, dense cubes for shaking (they don't over-dilute). Use large format ice (2" cubes or spheres) for rocks pours. Crushed or pebble ice for Mules and Smashes. Bring your own if you can — venue ice quality varies wildly.
Set up 5 glasses. Free pour 1oz into each with your speed pourer. Then jigger what you poured. The gap between what you think and what's actually in the glass is your lesson.
Serving a cocktail in the right glass isn't pretension — it affects aroma, temperature retention, and how the drink is perceived. For mobile events, you won't always have every glass, so knowing your priority order matters.
| Glass | Volume | Used For | Mobile Priority |
|---|---|---|---|
| Rocks / Old Fashioned | 8–10oz | Spirits neat/rocks, Old Fashioned, Negroni | ★★★★★ |
| Highball | 10–12oz | G&T, Mule, Mojito, Bourbon & Coke | ★★★★★ |
| Coupe | 5–6oz | Daiquiri, Sidecar, Gimlet, Manhattan | ★★★★☆ |
| Martini | 4–8oz | Martini, Cosmopolitan | ★★★☆☆ |
| Wine Glass | 12–16oz | Wine, Aperol Spritz, Sangria | ★★★★☆ |
| Champagne Flute | 6oz | Champagne, French 75, Mimosa | ★★★☆☆ |
| Shot Glass | 1–2oz | Shots, Tequila, Sambuca | ★★★☆☆ |
| Pint Glass | 16oz | Beer, Long Island, Shandy | ★★★☆☆ |
If you can only bring two glass types, bring Rocks and Highball. You can serve 80% of cocktails in those two. Coupes are your third priority — they signal craft and elegance at upscale events.
Store-bought syrups are fine in a pinch. House-made syrups are what separate good bars from memorable ones. These are your core four:
Lime juice and lemon juice should always be fresh-squeezed for events. Bottled juice is flat, bitter, and it shows. A hand citrus juicer and 2 pounds of limes takes 15 minutes of prep and transforms your cocktails. Never show up with Rose's Lime Juice for a Daiquiri event.
Pre-squeeze all citrus 24–48 hours before a large event and store in sealed squeeze bottles in your cooler. Saves crucial time during service and juice quality is still excellent.
Walk into any bar or event and speak the language fluently from day one.
40+ recipes organized by spirit and complexity. Every recipe comes with technique notes, variations, and the story behind the drink — because knowing a cocktail's history makes you a better bartender.
Garnish is the first thing a guest sees. At an event where guests are photographing their drinks, your garnish is free advertising. Take it seriously.
Pre-cut everything before service begins. Store wheels in water, wedges in a covered container, herbs in damp towels. At large events, have a dedicated garnish tray organized and within arm's reach. Reaching into a bag during service kills your flow.
Create a "signature garnish" for each event. For a wedding, a rosemary sprig + dehydrated citrus wheel. For a corporate event, a branded cocktail pick. Small touches become memorable moments guests post online.
The skills that get you hired. From writing your first quote to building a six-figure mobile bar operation — this is everything they don't teach in bartending school.
Underpricing is the #1 mistake new mobile bartenders make. You do the math, realize you made $8/hour, and you quit. Let's fix that before your first booking.
| Cost Item | Example |
|---|---|
| Your Time (setup + event + breakdown) | 6 hrs × $40/hr = $240 |
| Travel (mileage or gas) | $30–60 |
| Supplies consumed (napkins, straws, picks, garnish) | $20–40 |
| Wear on equipment | $10–20 |
| Insurance allocation | $15–25 |
| Minimum floor price (before profit) | ~$315–385 |
You are not "just a bartender at their party." You are a licensed professional, carrying insurance, showing up with a full mobile operation, creating a guest experience. Price accordingly. Clients who value quality will pay it. Clients who don't aren't your clients.
Every event starts with a consultation. This is your intake, your sales call, and your protection — all in one. A thorough consultation prevents 80% of day-of problems.
Plan for 1 drink per guest per hour for the first 2 hours, then 0.75 drinks/hr after. For a 4-hour event with 80 guests: (80×2) + (80×0.75×2) = 280 drinks. Add 15% buffer. Always round up on mixers, never on spirits (over-ordering spirits is expensive).
Your first 3–5 events can be friends' parties, family events, or charity fundraisers at a deep discount or free. Bring a photographer (or ask a friend). Capture everything. A beautiful portfolio photo of your bar setup is worth more than any ad you'll ever buy.
Use this interactive checklist before every event. Tap each item to mark it done.
Technical skill gets you hired once. Your service experience is what gets you referred. Learn how to read a room, manage a rush, handle difficult guests, and become the bartender clients call back.
A mobile bartender is part bartender, part host, part entertainer. You're often one of the first and last people guests interact with at an event. You set the energy.
Read the event type immediately: Is this a professional corporate event (formal, measured pours, quiet service) or a 30th birthday party (energy, personality, upsell on fun shots)? Dress, music, and the client's vibe when they greet you tells you everything.
Keep it short and genuine. A compliment, a question about the event, or a brief story about the cocktail you're making. Then let them go enjoy it. Bartenders who talk too much slow down the line and make introverts uncomfortable.
Stand with your shoulders open, not hunched over the bar. Smile when you make eye contact. Put your phone out of sight. These three things alone will change how guests perceive you.
This is not optional — it is your legal responsibility. If a guest appears intoxicated (slurring, unsteady, aggressive, or asking for multiple drinks rapidly), you must slow or stop service. Do it kindly:
Some guests will ask for off-menu cocktails, expect you to "just make something amazing," or push back on wait times. Your response: be warm, be clear, stay in control. "Absolutely — what flavors do you like? Sweet, sour, or spirit-forward?" Turning a complaint into a custom experience wins every time.
You'll spill a drink. You'll run out of a spirit. Your bar might tip. Own it immediately, fix it fast, and never let the client see you panic. What guests remember is how you handled it, not that it happened.
A signature cocktail menu is your value-add. It turns a bartender into an experience. Here's the framework I've used for 25 years.
Always include a non-alcoholic "mocktail" option — and make it just as beautiful. Never treat it as an afterthought.
For a wedding, name the signature after the couple's story — where they met, an inside joke, their honeymoon destination. "The Costa Rica Sunset." "The Rooftop Kiss." Guests drink the story, not just the cocktail.
This is one of the most common questions from new mobile bartenders and nobody talks about it directly. Let's fix that.
At open bar events: always have a tip jar. It's expected. Place it prominently but tastefully. A small jar with a $5 bill already in it establishes the norm. Tip jars at well-run open bars average $1–3 per guest, which on a 100-person event is a meaningful add to your rate.
On cash bars, tip is built into the transaction naturally. On digital payments (Square, Venmo), add a tip screen.
Some clients ask about gratuity upfront. Have a clear answer: "It's not required, but it's always appreciated. The standard for bartending services is 15–20% of the service fee." This removes the awkwardness and positions it professionally.
The non-negotiables. These rules exist to protect your guests, protect you legally, and protect your business. Every professional bartender knows these cold.
Requirements vary by state and municipality. At minimum, most US states require: a Food Handler's Card or Alcohol Server Certification (e.g., TIPS, ServSafe Alcohol, or your state's equivalent). Many states require a specific caterer's or mobile vendor's license for off-premise alcohol service. Some require a temporary event permit for each event you work. Research your specific state's ABC (Alcohol Beverage Control) laws. Do this before your first event — not after. Operating without proper licensing exposes you to fines, license revocation, and civil liability.
Dram shop laws hold alcohol servers legally responsible for damages caused by guests they over-served. If you serve an intoxicated guest who then drives and injures someone, you can be held civilly liable in most US states. This is why liquor liability insurance is non-negotiable for mobile bartenders. Typical coverage: $1M per occurrence, $2M aggregate. Cost: $300–800/year depending on your volume. It's the single most important business expense you'll make.
The legal drinking age in the US is 21. Check ID if a guest appears under 30 — the "when in doubt, card" rule protects you. Check: (1) expiration date — it must be current, (2) photo match — look at the person, not just the ID, (3) birthdate math — count it out, don't rely on glancing at a number, (4) security features — holograms, raised print, UV features vary by state but learn your state's features. Refuse service if you have any reasonable doubt. The consequences of serving a minor far outweigh any awkward moment.
Signs of intoxication include: slurred speech, loss of coordination, overly loud or aggressive behavior, glassy or unfocused eyes, difficulty making decisions, strong odor of alcohol, and repeated or confused questions. BAC of 0.08% is the legal limit for driving — but impairment begins well below that. Your job is not to police a number; it's to use your professional judgment. Trust your instincts. When in doubt, slow service, offer water and food, and monitor. A confident "I'm going to take care of you — let's start with water" said warmly is your best tool.
Your contract should include: service date, time, and location; number of guests and hours of service; what you are providing (labor only vs. labor + alcohol vs. full package); pricing and payment schedule; deposit amount and non-refund policy; cancellation terms (by either party); overtime rate if event runs long; confirmation that client has secured any necessary event permits; a clause stating you reserve the right to refuse service to any guest for safety reasons; and your liability limitations. Never work without a signed contract. A simple digital contract via DocuSign or PandaDoc costs under $25/month and protects you from thousands in disputes.
Keep fresh citrus juice refrigerated and use within 48 hours. Ice is a food — use a scoop, never your hands. Store garnishes covered and at safe temperatures (below 41°F). Dairy-based cocktails (Irish Coffee, cream drinks) must be kept cold and discarded after 2 hours at room temperature. Pre-batched cocktails with perishable ingredients follow the same rules. Clean your bar station regularly during service — citrus juice and sugar attract pests quickly. At outdoor summer events, be especially vigilant about temperature control. A food-borne illness at your event ends careers and creates liability.
This course gives you the foundation. The craft is built at the bar, one drink and one event at a time. Set up your kit, practice your shakes, perfect your two or three best cocktails — and take that first booking. The rest comes with reps.
